The Justice Department says Swiss bank UBS AG must reveal names of thousands of suspected American tax cheats because the bank violated U.S. law.
A court filing Tuesday in Miami urges U.S. District Judge Alan S. Gold to enforce a summons against UBS seeking the identities of about 52,000 people. U.S. officials say those are mostly wealthy Americans who used secret UBS accounts to hide income from the Internal Revenue Service.
UBS has claimed it cannot disclose the names without violating Swiss law. But U.S. officials say foreign law and tax treaties do not shield U.S. taxpayers from liability. The court filing says UBS “systematically and deliberately violated” U.S. laws.
